Meeting in Beijing

"Ladies and gentlemen, we are about to arrive at Beijing Capital International Airport. For your safety and comfort, please remain seated with your seatbelt fastened…"

Lu Zhou put away his notebook and pen.

He suddenly noticed the teenage boy next to him, who was wearing a baseball cap, was staring at his notebook.

Lu Zhou raised his eyebrows and smiled.

"Wondering what I was writing?"

The boy didn't seem to recognize Lu Zhou, so he nodded and spoke.

"Uncle, I think I've seen that formula before."

Lu Zhou laughed.

This little sh*t…

Calls me an uncle, then humble brags.

Seen this before?

You don't know who I am, but you've "seen" this equation before?

My as*!

Lu Zhou wanted to call him out but decided against it.
